You could probably try using egrep, but it depends how well you know the data. It may be possible to specify a pattern to match on the nth field and therefore match the records you want. It depends what you call a column. Do you mean fixed width, i.e. starting from character 6 or character 18 (seems unlikely with you sample) or is it space sparated, and if so, how do you handle multiple spaces.
If you mean "the last bit of a record" then you can use a $ to mark where the end of record is. You would code this as:-
Code:
string$
in file1. You may have to cater for it in other positions too.
Can you elaborate a bit more on what should match and what should not, including some variations in position/column on records. Perhaps someone better than I will come up with either a better pattern match or an awk to assist if I can go no further.
Thanks, in advance.
I hope that this helps,

Oh! I've been beaten by an awk already. I suppose it's better than being beaten by an Orc though!

Hey all,
So I have this challenge where I am attempting to compare record counts from within several different log files. I want input and output counts for each file, and I want to compare that with the result of the input/output comparison from a separate--but related file.

combine
COMBINE(1)COMBINE(1)NAME
combine - combine sets of lines from two files using boolean operations
SYNOPSIS
combine file1 and file2
combine file1 not file2
combine file1 or file2
combine file1 xor file2
_ file1 and file2 _
_ file1 not file2 _
_ file1 or file2 _
_ file1 xor file2 _
DESCRIPTION
combine combines the lines in two files. Depending on the boolean operation specified, the contents will be combined in different ways:
and Outputs lines that are in file1 if they are also present in file2.
not Outputs lines that are in file1 but not in file2.
or Outputs lines that are in file1 or file2.
xor Outputs lines that are in either file1 or file2, but not in both files.
"-" can be specified for either file to read stdin for that file.
The input files need not be sorted, and the lines are output in the order they occur in file1 (followed by the order they occur in file2
for the two "or" operations). Bear in mind that this means that the operations are not commutative; "a and b" will not necessarily be the
same as "b and a". To obtain commutative behavior sort and uniq the result.
Note that this program can be installed as "_" to allow for the syntactic sugar shown in the latter half of the synopsis (similar to the
test/[ command). It is not currently installed as "_" by default, but you can alias it to that if you like.
